Ticket lock

When lots of people want to use something at the same time, it can create chaos and confusion. It's like when all your friends want to play with your favorite toy at the same time, but there's only one toy to go around. That's where a ticket lock comes in!

A ticket lock helps keep things organized by making sure that only one person can use something at a time. It's like a ticket counter at a fair, where you have to wait in line and get a ticket before you can go on a ride.

With a ticket lock, different programs or parts of a computer can take turns using a resource, like the toy or the fair ride. They get in line and ask for a ticket, and the ticket lock makes sure that only one program can have the resource at a time. That way, no one gets left out or confused, and everything works smoothly.

So, a ticket lock is like a fair ticket counter for computer programs, helping them take turns using resources without causing chaos.
